mCookie-WiFi is WIFI communication module, which can connect other WIFI devices and communicate with CoreUSB via serial port.

==Features==
*Serial communication; 
*Available for the internet; 
*Small, stackable, open-source and cheap; 

==Specification==
*Way of communication: Serial port transmission with the default serial port D2(RX)、D3(TX); 
*Power supply: +3.3VDC 50mA; ；
*Status indicator; 

==Common AT Instruction==
*All AT instructions are ended with "\r\n ". 

*Common AT instruction: 
**AT+RST   Restart modules 
**AT+GMR  Check version info. 
**AT+CWMODE=3   Station & access point
***1 Station mode   
***2 AP mode 
***3 AP & Station

**AT+CWLAP   WIFI SSID list 

**AT+CWSMARTSTART=0   Start smart connection 
***0: Use AL-LINK  
***1: Use ESP-TOUCH
 ***2: Use AIR-KISS

**AT+CWSMARTSTOP    Stop smart connection 

**AT+CWJAP="<access_point_name>","<password>"   Add to a certain WIFI   

**AT+CIFSR    Display WIFI information 

**AT+CIPSTATUS  Acquire connection status  

**AT+CIPSTART=4,"TCP","baidu.com",80   Establish TCP/UDP connection

**AT+CIPCLOSE    Shut off TCP/UDP connection (Single connection) 

**AT+CIPCLOSE=5  Close multi-connection 

**AT+CIPMUX=1   Start multi-connection

*Download program 
**Stacke mCookie-WiFi and mCookie-CoreUSB, plug USB cable into mCookie-CoreUSB on one side and connect computer USB socket on the other side. Then, start Arduino IDE, copy the program above to IDE, select Microduino-CoreUSB in (tools) -> (Board) and choose the right serial number in (tools) -> (Serial). After that, please click button (√) on the top left of IDE and compile the program. Burn the program to the board after compiling by clicking button (->); 
*Open serial monitor and set "\r\n " and "115200 baud " 
*The notice of successful WIFI connection will pop up at first. 
*Enter AT instruction in the serial port and it will return "OK". 
*Enter website such as baidu.com in the serial port and it will return webpage data.

*Enter fixed instructions in the serial monitor and you'll see returned result, which can refer to common AT Instruction part. 
Such as:  
*AT+GMR
*AT+CIFSR
*AT+CIPSTATUS

*IDE tests program 

You can adopt HTTPGET program of _03_microduino_WiFi_ESP8266 from Microduino IDE example for testing. [[File:ESP8266-exampleCode.jpg|thumb|600px|center]]

Change your WIFI password in the code where there are SSID(WIFI name) and password setting.

*Download program  
**Stack Microduino-WiFi(ESP) with Microduino-Core+ and Microduino-USBttl, plug USB cable into mCookie-CoreUSB on one side and connect computer USB socket on the other side. Then, start Arduino IDE, copy the program above to IDE, select Microduino-CoreUSB in (tools) -> (Board) and choose the right serial number in (tools) -> (Serial). After that, please click button (√) on the top left of IDE and compile the program. Burn the program to the board after compiliing by clicking button (->)
* Open serial monitor and set "\r\n " and "115200 baud " 
*Firstly, you'll see notice of successful WIFI connection. 
*If you see content description, it means you have visited "www.baidu.com". [[File:ESP8266WiFi-exampleCode1.png|600px|center|thumb|Serial]]
